FM 30-26 Basic Field Manual, Regulations for Correspondents Accompanying U.S. Army Forces in the Field 1942-01-21
"The Army recognizes that correspondents perform an undoubted public function in the dissemination of news concerning the operations of the Army in time of war. Correspondents accompanying troops in the field occupy a dual and delicate position, being under the necessity of truthfully disclosing to the people the facts concerning the operations of the Army, and at the same time of refraining from disclosing those things which, though true, would be disastrous to us if known to the enemy. It is apparent that this important function can only be properly performed under reasonable rules and regulations."
